PlCTURE-MAT-CU TTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 286,422, dated October9, 1883.

Application filed August 4, 1853. (N0 model.)

To all whom it may concern.-

Be it known that I, EDWARD L. GAYLORD, a citizen of the United States,residing at Bridgeport, in the county of Fairfield and State ofConnecticut, have invented certain new and useful Improvements in MatCutting Machines; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as willenable'others skilled in the art to which it appertains to make and usethe same. I

My invention relates to certain novel and useful improvements in devicesfor cutting pictureniat-s and the like, and has for its object toprovide a device of this description in which the mat or other materialshall be firmly held. underneath the cutter, while at the same time thecutter-frame and knife shall be adjustable; and with these ends in viewmy invention consists in the details of construction and combination ofelements, hereinafter fully and in detail explained, and thenspecifically designated by the claims.

In order that those skilled in the art to which my invention appertainsmay more fully understand its construction and operation, I will proceedto describe the same in, detail, referring by letter to the accompanyingdrawings, forming a part of this specification, in which- Figure 1 is atop or plan view; Fig. 2, a cross-section taken through thecutter-frame, and'llig. 3 a side elevation.

Similar letters denote like parts in the several figures of thedrawings.

A is the frame, and B a guideway arranged thereon, and connected at eachextremity to fiat spring pieces C by means of bolts D, passed throughsaid guideway and springs. These bolts are riveted to the guideway andextended down through the block E, and are provided with nuts I! at.their extremities. Between the former of which is stationary, and thelatter adapted to turn freely around the bolt D. The contiguous surfacesof these disks are beveled or inclined, as shown, so that it will bereadily understood that by the manipulation of the movable disks H theguideway B is clamped down or loosened, as the case may be, for thepurpose presently explained.

I is the plate, arranged to travel 011 the guideway 13. Adjustablyattached to said plate by means of set-screw J isthc cutter-box carrierK. At the forward end of this carrier is pivoted the box L.

M is a set-screw, by means of which the box may be secured at anydesired angle. \Vithin this box is the tool-holder N, so arranged as toslide freely within said box.

0 is the cutting-tool, which is held in the desired position within theholder by means of the set-screw P and block Q.

In assembling the several parts of my improvement I place the toolwithin the holder, slide the block thereon, and, after adjusting thetool so as to cut to the desired depth, secure the parts by means of theset-screw P,

which operates through a frame, R, traveling in'ways at the sides of thetool-holder.

' The operation of my improvement is as follows: The mat is placed uponthe frame and underneath the guideway, and clamped in position byoperating the disks H. The plate K is adjusted out or in so as to bringthe cuttingtool in the proper position above the mat, and the boXL issecured in the desired position so as to cut at the required angle. Byexerting a downward pressure on the tool-holder, and

sliding the plate I along the guideway B, the

cutting-tool is forced through the mat and a cut made. The mat may beremoved by simply turning the disks H back to their normal position,when the action of the springs C will throw the guideway up and off fromthe mat. I

I do not wish to confine myself to the exact manner shown and describedof adjusting the several parts, as this may be varied without departingfrom the spirit of my invention.

What I claim as new, and desire to secure by Letters Patent, isr 1. In adevice for cutting mats for pictures and the like, the plate adapted 1oslide on the guideway, as described, and having secured thereto thedevices for supporting and holding the cutting-tool holder andcutting-tool, substantially as set forth.

2; The plate I, adapted to slide along the guideway B, in combinationwith the cutterbox. carrier adjustably attached to said plate,

swinging box L,too1-ho1der N, and adjustable In testimony whereof Iaffix my signature in cutting-tool 0 substantially as set forth andpresence of two Witnesses.
